TERN Weekly Pollen Count - Rocklea, Brisbane, Queensland 1994-1999

Brief description

The datafile, published by the Terrestrial Ecosystem Research Network (TERN) contains the composition and abundance of airborne pollen in the suburb of Rocklea, Brisbane, Queensland, Australia. The data was collected for the period between June 1994 to May 1999 as part of a research program that assessed pollen bioaerosols and relationships with meteorological parameters (see Green BJ, Dettmann M, Rutherford S, Simpson RW [2002]. Airborne pollen of Brisbane, Australia: a five-year pollen record, 1994-1999. Grana 41(4):242-250.). This forms part of a study of the Australian Aerobiology working group (Haberle, Bowman, Newnham, Johnston, Beggs, Buters, Campbell, Erbas, Godwin, Green, Heute, Jaggard, Medek, Murray, Newbiggin, Thibaudon, Vicendese, Williamson, Davies “The macroecology of airborne pollen in Australian and New Zealand urban areas” ).

Airborne pollen counts were derived from deployment of a seven-day Hirst-type volumetric pollen and spore trap and the instrument’s orifice elevated 2m above ground level. Several periods of motorized trap breakdown were experienced, but these were usually brief and accounted for a total of 117 days during the entire sampling period. The trap was calibrated to sample air at ten litres per minute and pollen was deposited onto tapes coated with a thin film of Dow Corning pressure-sensitive silicone adhesive (280A). The seven-day tapes were cut into daily lengths and mounted in Carberla’s solution on glass microscope slides. The entire surface area of each tape was scanned at magnifications of x250 using north +- south traverses and the pollen counts then converted to correspond to grains per m3 air as a daily mean value. The data is summed to provide an average weekly pollen count. Pollen identification was aided by reference to photomicrographs provided by Moss (1965), Grant Smith (1990), and Hjelmroos et al. (1999).
